Segmentation fault at opening file

[luislve17]

OS: Ubuntu 18.04 LTS

Hi
I tried to use your editor after cloning, all I did was:

cd Lite && make

Then when trying to open a file (like lite.c) I tried to do

./lite lite.c

And this is what came out:

[1]    8459 segmentation fault (core dumped)  ./lite lite.c

Using only ./lite works fine for creating new files, but after saving and trying to open again I get the same error

Edit:
Also, after this dump error, my terminal gets all messy, like termios settings weren't restored. For example, after the error trying to do a 'ls' prints the files all over the place.
